The ITU

3、 Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. Some 179 member countries, 84 telecom operating entities, 145 scientific and industrial organizations and 38 international organizations participate in ITU-T which is the body which sets world telecommunications stand

4、ards (Recommendations). The approval of Recommendations by the Members of ITU-T is covered by the procedure laid down in WTSC Resolution No. 1 (Helsinki, 1993). In addition, the World Telecommunication Standardization Conference (WTSC), which meets every four years, approves Recommendations submitte

5、d to it and establishes the study programme for the following period. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. The text of ITU-T Recommendation X.881 was approved on 1st of July 1994. The

6、 identical text is also published as ISO/IEC Intemational Standard 13712-2. NOTE In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.

17、i Summary This Recommendation I International Standard provides the OS1 realizations of the abstract concepts of the Remote Operations Service (ROS). it describes the services provided by ROSE and the mappings of these services onto those provided by the Association Control Service Element (ACSE), t

18、he Reliable Transfer Service Element (RTSE) and the presentation layer. ii ITU-T R the Remote Operations ASE (ROSE) which drives the general-purpose protocol required to invoke and report returns of arbitrary operations; information transfer ASEs concerned with the establishment and release of assoc

19、iations where necessary, and the communication of the ROSE protocol control information (PCI). In the OS1 realization, such ASEs are the Association Control Service Element (ACSE), the Reliable Transfer Service Element (RTSE) used together with the services of the Presentation layer. This Recommenda

20、tion I International Standard focuses on the derivation of ROSE-based application context specifications, the service provided by ROSE, and the way that ROSE is used. This Recommendation I International Standard is a revision of CCRT Rec. X.219 I ISO/IEC 9072-1. The existing usage of ROSE in connect

21、ion with ACSE, RTSE and the Presentation layer as defined in CCIT Rec. X.219 I ISO/IEC 9072-1 remains valid after this revision. This revision makes no change to the ROSE PCI. Annex A forms an integral part of this Recommendation I International Standard. Annexes B and C do not form an integral part

23、T (ROSE) SERVICE DEFINITION 1 Scope This Recommendation I International Standard provides the framework for the realization as an OS1 application context of the abstracts concepts of operation package and association contract defined in ITU-T Rec. X.880 I ISOAEC 13712-1. Such an application context

24、is described in terms of a collection of application service elements, in particular the Remote Operations Application Service Element (ROSE), which drives the general purpose protocol for invoking and reporting the returns of arbitray operations. The terms, definitions, and mechanisms defined in IT

25、U-T Rec. X.880 I ISO/IEC 13712-1 apply here and are specialized for an OS1 realization as specified in this Recommendation I Intemational Standard. This Recommendation I International Standard focuses on the services provided by ROSE, and the way ROSE is used. The ROSE services are provided by the u

26、se of the ROSE protocol (specified in a companion Recommendation I International Standard, ITU-T Rec. X.882 I ISO/IEC 13712-3). in conjuction with the Association Control Service Element (ACSE) services (ITU-T Rec. X.217 I ISOAEC 8649) and the ACSE protocol (ITU-T Rec. X.227 I ISO/IEC 8650-1 and IT-

27、T Rec. X.237 I ISOAEC 10035-I), and, optionally, the Reliable Transfer Service Element (RTSE) services (IT-T Rec. X.218 I ISO/IEC 9066-1) and the RTSE protocol (ITU-T Rec. X.228 i ISOIEC 9066-2). and the Presentation service (ITU-T Rec. X.216 I ISOAEC 8822). A No requirement is made for conformance

28、to this Recommendation I International Standard. 2 Normative references The following ITU-T Recommendations and International Standards contain provisions which, through reference in this text, constitute provisions of this Specification.
